Application filed Elm/"ember 2S, 1919.

'c all 15 Hit it may concern: -e it known that W, men and r CHARLTON ROBINSON, subjects oil": l lis ll'iajesty the King or England, residents of London, in the county oi' ll'liddlesex and liingcom of England, have invented certain new and useful In provernents in and Relating to Bakers "Ovens, or which the following is a specification.

Our invention relates to improvements in baking ovens of the drawplate type for baking bread and the like, and consists essentially of a drawplate oven heated by steam tubes or by hot air, and formed with any number o1 separate decks or baking compartments as required, a hinged flap door being'provided for each deck to inclose the baking space, and an outer packed door to inclese the whole oven and in conjunction with the oven we provide an independent trolley formed with decks corresponding e2;- actly with the'deck levels in the oven. On each deck level of the trolley are guide rails, on wk traverses a skeleton framed baking sole. it his sole is actually the drawplate on which the baking trays are placed. At suitable intervals are angle bars for guiding and supporting the baking trays, the angle bars being arranged at convenient intervals to accommodate the particular product to be baked or to the method preferred of charging the soles. Continuous with the guide rails on the trolley are similar guide rails fixed on the inside plates of the oven, and on to these rails in the oven the skeleton framed baking soles are wheeled from the trolley into the oven. @r it may be preferred to mount the wheels on the sides or the oven and the troll y and to mount the guide rails on the skeleton trained baking soles. Formed on the fore part of the trolley at each deck level are horns, and when the trolley is moved up to the oven, these horns project against the lap doors, which they lift and sustain in the open position while the baking soles are being transferred from the trolley into the oven. When the Greece HENRY bakin oractice is such thatit is desirable 1 b 1 to cnarge one or otner of the compartments separately, the horns on the trolley may be omitted and the flap doors mayl 'be arranged to be opened by hand levers or any other convenient method.

According to our invention the method of its working is as follows:--The trolley be- Specmca'iou of Letters Patent.

ing in a convenient place for charging and the baking soles in their respective positions on the trolley, the baking trays containing the goods to be baked are slid on to the angle bars of the baking soles, the outer doors of the oven are opened and the trolley is moved up to the front of the oven. The projecting horns open the flap doors, and the baking soles are propelled from the trolley into the oventhe propulsion of the baking soles may be ei'i ected by hand or by rollers or other convenient method. The trolley is then withdrawn and the flap doors automatically close. The outer doors are closed by hand. when the baking process is completed the trolley is wheeled up to the oven again and tie baking soles are withdrawn from the oven on to the trolley and run to a convenient place to be discharged.

Our invention will be readily understood by reference to the accompanying drawings, in which:-

Figure l is a vertical section of the oven; 2 is a front elevation with one o1 the outer doors shown open;

3 is a horizontal. sectional plan showing on one half the baking sole, and on the oth er halt the steam heating tubes; and
